Reliability & Common Issues
The Nissan Altima has a mixed reputation for reliability. While some generations are known for their dependability, others have experienced common issues. Here's a breakdown:
Engine Issues
- QR25DE (2.5L Four-Cylinder): This engine, found in the third, fourth, and fifth generations, is prone to excessive oil consumption. Regular oil level checks are crucial to prevent engine damage. Catalytic converter failure is also a common issue due to oil contamination.
- VQ35DE (3.5L V6): Generally a more reliable engine, but some models have experienced timing chain issues and oil leaks.
- VC-Turbo (2.0L Four-Cylinder): This engine is relatively new, so long-term reliability is still being assessed. Early reports suggest potential issues with the variable compression system, which can be complex and expensive to repair.
Transmission Issues
- CVT (Continuously Variable Transmission): The CVT transmission used in many Altima models is a common source of problems. Symptoms include slipping, jerking, and a complete failure of the transmission. Regular CVT fluid changes are essential, using only Nissan-specified fluid. Extending the recommended service interval significantly increases the risk of failure. Many owners have reported CVT failures well before 100,000 miles.
Other Common Issues
- Electrical Issues: Some Altimas have experienced issues with the electrical system, including problems with the alternator, battery, and sensors.
- Suspension Issues: Worn suspension components, such as struts and control arms, are common, especially on older models.
- Rust: Depending on the climate and maintenance, rust can be a concern, particularly in areas with road salt. Check the undercarriage and body panels for signs of rust.
- Air Conditioning: AC compressor failure and refrigerant leaks are not uncommon.
Driving Experience
The Nissan Altima offers a comfortable and generally pleasant driving experience. Here's a summary of the pros and cons:
Pros
- Comfortable Ride: The Altima is known for its smooth and comfortable ride, making it a good choice for daily commuting and long trips.
- Fuel Efficiency: The four-cylinder engines, particularly the 2.5-liter, offer good fuel economy.
- Spacious Interior: The Altima provides ample space for passengers and cargo.
- Available Technology: Newer models offer a wide range of technology features, including advanced safety systems and infotainment options.
Cons
- CVT Transmission: The CVT transmission can feel unresponsive and unrefined compared to a traditional automatic transmission. It also contributes to some of the reliability concerns mentioned earlier.
- Handling: While comfortable, the Altima is not known for its sporty handling. It's more focused on providing a smooth and predictable ride.
- Engine Noise: Some drivers find the engine noise, particularly from the four-cylinder engine, to be excessive.
Buying Advice
When buying a used Nissan Altima, here's some advice to help you make an informed decision:
Years to Consider
- 2018 (Fifth Generation - Last Year): Generally considered a relatively reliable year within the fifth generation. By this point, some earlier issues had been addressed. Look for well-maintained examples with documented service history.
- 2019+ (Sixth Generation): The sixth generation offers a more modern design and advanced technology. While it's newer and potentially more expensive, it might be worth the investment for the updated features and styling. Be aware of the newer VC-Turbo engine and potential long-term reliability.
Years to Avoid (or Proceed With Caution)
- 2002-2006 (Third Generation): These models are prone to rust, and the QR25DE engine has a high risk of oil consumption and catalytic converter failure.
- 2007-2012 (Fourth Generation): Similar issues with the QR25DE engine and potential CVT problems. Inspect thoroughly.
- 2013-2018 (Fifth Generation) with High Mileage: CVT problems are a significant concern. Get a pre-purchase inspection, particularly of the transmission.
Key Things to Check Before Buying
- Maintenance Records: Look for a car with a complete and well-documented maintenance history. Pay close attention to oil change intervals and CVT fluid changes.
- CVT Condition: Test drive the car thoroughly and pay attention to the transmission's performance. Look for signs of slipping, jerking, or unusual noises. If possible, have a mechanic inspect the CVT.
- Engine Condition: Check the oil level and look for signs of oil leaks. Listen for any unusual engine noises.
- Rust: Inspect the undercarriage, body panels, and around the wheel wells for signs of rust.
- Pre-Purchase Inspection: Always get a pre-purchase inspection from a qualified mechanic before buying any used car.
By following these guidelines, you can increase your chances of finding a reliable and enjoyable Nissan Altima that meets your needs and budget.
